Automatic faucets
First Claim
1. An automatic faucet comprising:
- a housing constructed to receive at least one water inlet conduit and having a spout for delivering water;
a valve module including a valve controlled by an electromagnetic actuator for controlling the water flow from said spout;
a sensor module constructed to provide sensor data influenced by a user;
a control module constructed to control opening and closing of said valve by providing signals to said electromagnetic actuator, andsaid control module constructed to receive sensor data from said sensor module and execute a sensing algorithm that keeps track of noise signal level and dynamically adapts a signal threshold, said sensing algorithm tracking signal trend to determine presence of a user.

Abstract
An automatic faucet includes a housing constructed to receive at least one water inlet conduit and having a spout for delivering water. The automatic faucet includes a valve module, a sensor module, a battery module, a turbine module, and a control module. The valve module includes a valve controlled by an electromagnetic actuator for controlling the water flow from the spout. The sensor module is constructed to provide sensor data influenced by a user. The control module is constructed to control opening and closing of the valve by providing signals to the electromagnetic actuator. The control module is also constructed to receive sensor data from the sensor module and execute a sensing algorithm. The control module is also constructed to execute a power management algorithm for managing electrical power generated by the water turbine and provided to and from the battery.
